This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized.

• Reactive species as intracellular messengers
• Redox regulation of cellular responses
• Clinical implications of redox signaling and antioxidant therapy

Thiol Redox Transitions in Cell Signaling, Part A, along with its companion (volume 475), presents methods and protocols dealing with thiol oxidation-reduction reactions and their implications as they relate to cell signaling. This first installment of Cadenas and Packer's two-volume treatment specifically deals with glutathionylation and dethiolation, and peroxide removal by peroxiredoxins/thioredoxins and glutathione peroxidases.

The critically acclaimed laboratory standard for 40 years, Methods in Enzymology is one of the most highly respected publications in the...

From an August 1992 workshop on the Greek island of Spetsai, 28 papers focus on the regulation of intracellular calcium levels, the second messengers derived from inositol lipids, and the specific phospholipase C isozymes involved in those processes. The sections cover the components of signal trans

Mitochondria have traditionally been associated with metabolic functions; however recent research has uncovered a central role for these organelles in cell signaling, cell survival, and cell death. Mitochondrial dysfunction is a factor in a myriad of pathophysiological conditions, including age-related neurodegenerative disorders, cancer, metabolic syndrome, and cardiovascular disease. Mitochondrial Signaling in Health and Disease examines themes essential for the maintenance of the mitochondrial redox (reduction-oxidation) energy axis.

This book is based on two keywords: Bioradical and ESR. Bioradical is a newly coined word which encompasses paramagnetic species in biological systems, such as active oxygen radicals and transition metal ions. Research on the structure and function of bioradicals has been attrac ting growing attention in the field of biological science, and comprehensive investigations from many fields are helping to understand the real features of these species. ESR spectroscopy also has interdisciplinary features in that its techniques have been applied to many fields, ranging from physics to medicine. It...

Free radicals appear to play a mojor role in many neurological (and non neurological) dieseases. Both acute and degenerative disorders are thought to involve free radicals reactions in tissue injury (for a list see this book page 18). This issue is very important for basic science and for therapeuthic approach as well. In order to review and discuss the place of free radicals in psychiatry and neurology, a joint meeting was initiated by the World Health Organization and the Fondation Ipsen in Paris on June 17-18,1991. This book contains the papers presented during this meeting. Although the...

A NATO Advanced Study Institute on "Molecular Mechanisms of Transcellular Signaling: from the Membrane to the Gene" was held on the Island of Spetsai, Greece, from August 15- 27, 1994. The aim of this Institute was to bring together researchers in the field of signal transduction mechanisms, transcription factors and gene regulation with those actively involved in studies on the implications of oxygen radicals and antioxidant defence mechanisms for cell function. As diverse as these fields may be, the emergence of their interconnection during the course of the Institute was an eye-opener for...

A NATO Advanced Study Institute on "New Developments in Lipid-Protein Interactions and Receptor Function" was held on the Island of Spetsai, Greece, from August 16-27, 1992. This Institute was organized to bring together researchers in the field of membrane organization and dynamics with those actively involved in studies on receptor function, signal transduction mechanisms and gene regulation. 2 Presentations and discussions focussed on the regulation of intracellular Ca +-levels, on the second messengers derived from inositol lipids and on the specific phospholipase C isozymes involved in...

A NATO Advanced Study Institute on "New Developments and Methods in Membrane Research and Biological Energy Transduction" was held in order to consider some of the most recent developments in membrane research methodologies and results, with particular emphasis on studies of biological energy transduction. The partic ipants in the Institute dealt with three general areas of membrane study: membrane structure (with emphasis on lipid and protein components), membrane component assembly (with particular emphasis on mitochondria and chloroplasts), and the specialized functions of certain membrane...

Twenty years ago, the enzyme superoxide dismutase which uses the superoxide radical anion as its specific substrate was reported. With this discovery was born a new scientific field, in which oxygen, necessary for aerobi c 1 ife on thi s planet, had to be cons i dered also in terms of its toxicity and stresses. This stimulated the search for knowledge of active oxygen species in biology and medicine. Superoxide and other reactive oxygen species are now implicated in many disease processes. Major advances have been achieved during these past years with respect to free radical generation and...
